Application .filed January In farminga tractor is commonly employed for pulling machinery' and Vfarm wagons or trucks to places in fields where such tractor and machinery are to be used.

from the farm house andoccasions often occur where, iti's necessary for a hand, or supervisortobreturn from the lield to the farm house or' to make other trips necessary in conducting the work. It may therefore be considered the primary object of this in vention to provide a draw bar between a motor,actuated vehicle, such as is used by the superintendent or the like and a truck or other vehicle which is drawn to the work by the tractor, Vso that the `first mentioned 'vehicle may be readily detached from the remainder of the train of .vehicles and em-v ployed for making return trips to the farm house, trips necessary in other .parts of the field, and as a matter-of-fact, any journeys'.

necessary or desirable in farming. pursuits.

A A further object is the provision of a draw bar for this purpose which can be easily attached to a velilcle or. implement which is drawn by a tractor and to a motor4 propelled vehicle, and which is of a construe tion as to, permit of a vertical yielding be tween the two vehicles, incident to the pasf sage thereof over rough ground, but which will accurately guide the drawn vehicle so that thev same will accurately pursuej the path taken by the remainder of the train'of vehicles. O' l i A still further object is theprovision of a draw bar for this purpose which, when not required for use,-may remainV a fixture on the motor propelled vehicle and which will in noawise interfere with the steering or propulsionof such vehicle.

A still further object is the provision of a draw bar for this purpose ,that is of a simple construction. cheaply manufactured, easily installed, and thoroughly eilicient for its purposes. z

To the attainment of the foregoing objects and others which will appear as` the nature of the inventionisbetterunderstood, the improvement -further resides ilr` certain novel features of construction, combination and operative association of parts, a

' satisfactory embodiment of which is .illustrated by the accompanying drawings. In the drawings: l

the application ofthe improvement, parts 'Figure 2f -a sectional view approximately perspective view of the nection with farming implements and ory dinary inotor propelled vehicles, -it is to be understood that I do not wish tobe restricted to this particular use, as the draw bar maybe successfully employed in connection with other vehicles'.

In the drawings, the numerals 1 desig, I

nates a farm wa 'on from which the draft animals'are detac ed and which is designed to be hitched to any wheeled farming implement that in lturn is hitched'to a tractor. To the rear bolster 2 of the wagon 1, I attach a bracket. The bracket has a substantially U-shaped body whose parallel arms are disposed for contact with the opposite sidesA of the bolster and through these arms 'and through the bolster there is passed a; ""securingelement' 3, such as a bolt on which is threaded a nut. The bracket, at its lower and rear cornery is formed with an outwardly extending eye 4., l 'IhegmotorA driven vehicle to be, drawn by the train of vehicles to which the tractor is attached is preferably of the ordinary small type of automobiles commonly known as the Ford", although,'itwi1l be apparent as-the description progresses that the improvement "maybe applied'uponother types of automobiles.` The motor ydriven vehlcle or automobile is broadly indicated by the numeral los - .and 2 8 ofl the drawbar Sections there is a gaged by the ordinarynuts, and these bolts arein contacting engagementwith the inner and outer faces of\ -t he channeled axle 6. This frictional engagement'of the-bolts the axle hold the plates against movement in any direction on said axle. By Areference to the drawings it will b'e seen that the outer edges of the plates are rounded inwardly from thecenter to the ends thereof, and these portions of the vplates are provided 'with aligning openings11.

The numeral 12 designatesa draw bar section. This member l2-haS its upper face flat, but is increasedin thickness from a' from.. one ofv its ends to its -)oin't a .distance other end, and the widened or thickened end hingedly securi block member 14. A

Theblock, onthe rear face the arm' 16 and both the armsl and 17 are vto be provided with aligning openings 18 andi 19, respectively, wliile the arm 16 has' opening 20, adiacent tozits outer end. AThe a second arms'l and 17 of therblock 14 lare designed i through the aligning openings18 and 19-and there isarranged a substantially-Ushaped clip V22. Thisclip is firmly. bolted on the rod designed'to register with the opening 20 in of the] block `member 14 and anda drawn vehicle, comprising two sections,
